IEC 60644-2019 汽車(chē)電路應用的高壓熔斷絲連接線(xiàn)規范 Specification for high-voltage fuse-link for motor circuit applications

This document applies to fuse-links complying with IEC 60282-1 that are used with motors started direct-on-line on alternating current systems of 50 Hz and 60 Hz. 
Fuse-links according to this document are intended to withstand normal service conditions and motor starting pulses. 
The purpose of this document is to standardize time-current characteristics and to formulate pulse withstand requirements regarding testing.   
This document also applies to fuse-links used with motors that use assisted starting when appropriate care has been taken with selecting the rated current of the fuse-link (using advice from 5.2.3 of IEC TR 62655:2013 and from the fuse manufacturer).dition 2.1 2019-09 CONSOLIDATED VERSION VERSION CONSOLIDéE colour inside Specification for high-voltage fuse-links for motor circuit applications Spécification relative aux éléments de remplacement à haute tension destinés à des circuits comprenant des moteurs IEC 60644:2009-08+AMD1:2019-09 CSV(en-fr) THIS PUBLICATION IS COPYRIGHT PROTECTED Copyright ？ 2019 IEC, Geneva, Switzerland All rights
